I have been searching for a guide for configuration...any hints would be greatly appreciated..TY

What you want isn't provided by Twonkey. Login to your router's webpage, typically at 192.168.1.1, click "External Storage" and looks for the "Folder Sharing" section. There you can set up folders to be browsable from your PC and create user accounts to control who can see them.
